This application claims the benefit of priority to Taiwan Patent Application No. 106134749, filed on Oct. 11, 2017. The entire content of the above identified application is incorporated herein by reference.

Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein. All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference.

The present disclosure relates to a slide rail bracket, and more particularly to a slide rail bracket used in a slide rail such as a drawer slide rail or a server slide rail for installing a slide rail on a rack column of a rack.

With the advantages of having smooth movements and stable structures, roller slide rails are widely used in cabinets, system furniture, server cabinets, display brackets and slide racks of other electronic products. In order to facilitate installation of the slide rail on the rack column of the cabinet, the conventional slide rail is usually provided with a bracket at both ends with the two ends of the slide rail being fixedly positioned on the rack column by the bracket.

Most of the conventional slide rail brackets are provided with two positioning pins at the front end of the main body of the bracket, and the two positioning pins can be engaged in the positioning holes arranged in a row on the rack column, thereby fixedly positioning the bracket on the rack column. However, since there is a wide variety of racks on the market and the dimensions of column positioning holes used in racks of different brands also differ in size, when the slide rail brackets are used in the rack columns with different specifications, different positioning pins need to be applied.

In order to overcome the above issues, some slide rail brackets on the market use positioning bolts with two different diameters so that the slide rail brackets can be used with columns having positioning holes of different sizes at the same time. While the positioning bolt of this kind of slide rail bracket can be quickly engaged in the positioning hole of the rack column when assembling the bracket on the rack, the positioning bolt cannot be smoothly withdrawn from the positioning hole of the rack column when disassembling the bracket from the rack. Tools may need to be further used to withdraw the positioning bolt from the positioning hole so that the bracket can be removed from the rack column, which causes inconvenience in use.

In addition, the conventional slide rail bracket is not equipped with a buckle device for a locking device of the slide rail. Therefore, when the slide rail with the locking device is used, an additional buckle device is also required, which causes inconvenience in use.

Based on the above, it has become an important issue in the art to solve the above problems through improvements in the structure of the slide rail bracket.

An object of the present disclosure is to provide a slide rail bracket which can be quickly installed or disassembled without using tools during installation or disassembly. Another object of the present disclosure is to provide a slide rail bracket which can be used with racks of different specifications and can be used in a slide rail locking device.

The present disclosure provides a slide rail bracket used to be installed on a slide rail to fix the slide rail to a rack column of a rack. The slide rail bracket includes: a main body and a slide component. The main body has a front end, a rear end, an accommodating portion provided inside the main body, two through holes disposed at the front end of the main body, the two through holes being parallel to each other and extending from the front end of the main body to the accommodating portion. A slide component includes a slide block and two positioning bolts. The slide block is slidably disposed in the accommodating portion and is slidable back and forth along a direction parallel to the two through holes; the two positioning bolts are disposed on the front end of the slide block and respectively penetrate into the two through holes. When the slide block is displaced near the front end of the main body, the two positioning bolts protrude from the outer side of the front end of the main body. A first diameter portion and a second diameter portion are respectively provided at the front end of the two positioning bolts. The first diameter portion and the second diameter portion are coaxial with each other, the diameter of first diameter portion is smaller than the diameter of second diameter portion, and the first diameter portion is disposed at the front end of second diameter portion. At least one elastic member is disposed between the accommodating portion and the slide block, and used to push the slide block to displace toward the front of the main body.

The beneficial effect is that the slide rail bracket of the present disclosure can be applied to rack columns having positioning holes of different sizes at the same time without the need for tools during installation and disassembly, so that the convenience of use can be effectively improved.

Referring to FIG. 1, the present disclosure provides a slide rail bracket 2 to be installed at the two ends of a slide rail 1. By the slide rail bracket 2, the slide rail 1 may be quickly disassembled or installed on a rack column of a rack.

Referring to FIG. 2 to FIG. 4, the slide rail bracket 2 of the present disclosure mainly includes: a main body 10, a slide component 20, two elastic members 23 disposed between the main body 10 and the slide component 20, a cover plate 30 and a connecting seat 31 disposed on a side surface of the main body 10.

Referring to FIG. 2 and FIG. 3, the main body 10 in this embodiment is substantially rectangular. An accommodating portion 11 is provided inside the main body 10, and two through holes 13 are disposed at the front end of the main body 10. The two through holes 13 are parallel to each other and extend from the front end of the main body 10 to the accommodating portion 11. A locking bolt hole 14 is defined between the two through holes 13 at the front side surface of the main body 10. The locking bolt hole 14 is to allow a movable inner rail of the slide rail 1 to be locked into the locking bolt hole 14 by a screw, so as to fixedly position the movable inner rail of the slide rail 1. In addition to being used to fixedly position the movable inner rail of the slide rail 1, the locking bolt hole 14 also allows a server rack on the slide rail 1 to be locked into the locking bolt hole 14 through a screw so as to fixedly position the server.

Since a side surface of the accommodating portion 11 of the main body 10 is open, the slide component 20 and the two elastic members 23 can be disposed in the accommodating portion 11 of the main body 10 from the open side of the accommodating portion 11. The cover plate 30 is fixed to the main body 10 corresponding to the open side of the accommodating portion 11 by screws, so as to close the open side surface of the accommodating portion 11 and limit the slide component 20 and the two elastic members 23 in the accommodating portion 11. In this embodiment, the cover plate 30 is made of a metal plate, and the rear end of the cover plate 30 is connected to a connecting seat 31. The shape of connecting seat 31 complements that of the front or rear end of the slide rail 1 and can be fixedly connected with the front or rear end of the slide rail 1 so as to install the slide rail bracket 2 of the present disclosure on the front or rear end of the slide rail 1 (as shown in FIG. 1).

Referring to FIG. 2 and FIG. 3, the slide component 20 is slidably disposed on the main body 10 and includes a slide block 21 and two positioning bolts 22. The slide block 21 is slidably disposed in the accommodating portion 11 and is slidable back and forth along a direction parallel to the two through holes 13. The two positioning bolts 22 are disposed on two sides of the front end of the slide block 21 and respectively penetrate into the two through holes 13. Therefore, the two positioning bolts 22 can move back and forth along the slide block 21 and are retractably accommodated in the two through holes 13.

In this embodiment, the slide block 21 complements the accommodating portion 11 in shape. The slide block 21 is restrained and guided by an inner side wall of the accommodating portion 11 so that the slide block 21 can move back and forth along a direction parallel to a central axis of the two through holes 13. Referring to FIG. 5, FIG. 6 and FIG. 7, FIG. 8, when the slide block 21 moves back and forth in the accommodating portion 11, the two positioning bolts 22 are also driven to move by the slide block 21. When the slide block 21 moves near the front end of the accommodating portion 11, the two positioning bolts 22 protrude from the front end of the main body 10 (as shown in FIG. 5 and FIG. 7). When the slide block 21 moves near the rear end of the accommodating portion 11, the two positioning bolts 22 are guided by the slide block 21 and retract to the inner side of the main body 10 (as shown in FIG. 6 and FIG. 8).

Referring to FIG. 3, FIG. 5 and FIG. 6, when the slide block 21 is assembled in the accommodating portion 11, two spaces are reserved in the accommodating portion 11 respectively at two sides of the slide block 21. The two elastic members 23 are respectively disposed in the two spaces. In this embodiment, the two elastic members 23 are coil springs, and two ends of the two elastic members 23 respectively disposed between and in contact with the inner side wall of the accommodating portion 11 and rear side surfaces of the two positioning bolts 22. Through the elasticity of the two members 23, the slide block 21 and two positioning 22 are pushed so that the two positioning bolts 22 remain protruding from the outer side of the main body 10.

Referring to FIG. 4, a toggle portion 213 is provided on a side surface of the slide block 21 opposite to the cover plate 30, an opening portion 12 is disposed on a side surface of the main body 10 corresponding to the cover plate 30. The toggle portion 213 corresponds in position to the opening portion 12 of the main body 10, and the toggle side 213 is exposed from the opening portion 12. The function of the toggle portion 213 is to enable a user to toggle the toggle portion 213 with a finger so that an operator can control the slide block 21 and the two positioning bolts 22 to move back by pushing the toggle portion 213 toward the rear end of the main body 10; therefore, the two positioning blots 22 are retracted into the inner side of the main body 10.

Referring to FIG. 2 and FIG. 3, in this embodiment of the present disclosure, two sides of the front end of the slide block 21 respectively have a connecting plate 211. The direction of two connecting plates 211 is substantially perpendicular to the two positioning bolts 22. The rear ends of the two positioning bolts 22 are respectively provided with a connecting slot 223. The widths of two connecting slots 223 complement the two connecting plates 211 so that the two connecting plates 211 engage in the two connecting slots 223, thereby combining the two positioning bolts 22 on the connecting plates 211 at two sides of the front end of the slide block 21. In this embodiment, a positioning slot 224 is further disposed on one of inner side walls in the connecting slots 223 of the two positioning bolts 22. The two positioning slots 224 and the two connecting slots 223 extend in directions perpendicular to each other. At the same time, a positioning portion 212 is respectively disposed on the two connecting plates 211 corresponding to the positions of two positioning slots 224. The two positioning slots 224 complement the two positioning portions 212 in shape, and when the two connecting slots 223 are engaged with the two connecting plates 211, the two positioning portions 212 are engaged in the two positioning slots 224.

When the two positioning bolts 22 are assembled on the two connecting plates 211 of the slide block 21, the operation of the two positioning portions 212 and the two positioning slots 224 can block the movement of the two connecting slots 223 and the two connecting plates 211 along a direction perpendicular to the two positioning bolts 22, so as to prevent the two connecting plates 211 from being disengaged from the two connecting slots 223.

It should be noted that in this embodiment, the two positioning bolts 22 of the slide component 20 are separate structures from the slide block 21. However, in other embodiments, the two positioning bolts 22 may be integrally formed with the slide block 21, and is not limited to the disclosed structure in this embodiment.

Referring to FIG. 3, FIG. 4 and FIG. 7A and FIG. 7B, the front ends of the two positioning bolts 22 form a first diameter portion 221 and a second diameter portion 222. The first diameter portion 221 and the second diameter portion 222 are coaxial with each other. The first diameter portion 221 is protrudingly disposed on the surface of front end of the second diameter portion 222. The diameter of first diameter portion 221 is smaller than the diameter of second diameter portion 222.

Referring to FIG. 7A and FIG. 7B, the first diameter portion 221 and the second diameter portion 222 at the front end of the positioning bolt 22 respectively cooperate with a positioning hole 51a or 51b of a rack column 50 to fixedly position the slide rail bracket 2 onto the rack column 50. In this embodiment, since the outer diameter of the first diameter portion 221 is cylindrical, the first diameter portion 221 can complement the circular positioning hole 51a having a small diameter. Since the diameter of the second diameter portion 222 is larger than the diameter of the first diameter portion 221, the second diameter 222 can complement the square positioning hole 51b having a larger diameter. Since the front ends of the two positioning bolts 22 simultaneously have the first diameter portion 221 and the second diameter portion 222 complementing the positioning hole 51a or 52b of different specifications, it is unnecessary to change the positioning bolt 22 of the slide rail bracket 2 of the present disclosure when the slide rail bracket 2 is assembled on rack columns of different specifications, thereby improving the convenience of use.

Further, in the slide rail bracket 2 of the present disclosure, a buckle component 40 is disposed at a side surface of the main body 10. Referring to FIG. 4, FIG. 7A and FIG. 7B, the buckle component 40 is disposed at a side surface of the main body 10 and extends beyond the front end of the main body 10. A buckle slot 41 is disposed at a side surface of the buckle component 40 facing the rack column 50 and corresponds in position to the rack column 50. The buckle slot 41 engages with an edge of a side surface of the rack column 50 facing the buckle component 40 when the slide rail bracket 2 is assembled on the rack column 50, thereby fixedly positioning the main body 10 of slide rail bracket 2 onto the rack column 50.

Referring to FIG. 8A to FIG. 8C, during the installation of the slide rail bracket 2 and the buckle component 40 onto the rack column 50, first, the positioning bolts 22 of the slide rail bracket 2 are abut against the rear side surface of the rack column 50; then, an operator pushes the main body 10 of the slide rail bracket 2 toward the rack column 50 so that the front end of the main body 10 abuts against the rear side surface of the rack column 50, and the two positioning bolts 22 retract back to the inside of the main body 10. Then, the main body 10 is pushed near the rack column 50 so that the buckle slot 41 on the buckle component 40 engages with the edge of the rack column 50. Then, the main body 10 is moved up and down such that the centers of the two positioning bolts 22 are aligned with the positioning hole 51a or 51b of the rack column 50, and the two positioning bolts 22 can be pushed by the elastic force of the elastic member 23 so that the first diameter portion 221 or the second diameter portion 222 of the front end thereof can be engaged into the positioning hole 51a or 51b.

After the buckle slot 41 of the buckle component 40 engages with the edge of the rack column 50, the main body 10 is fixedly positioned against the rear side surface of the rack column 50, such that the slide rail bracket 2 and the rack column 50 cannot be displaced back and forth to prevent the two positioning bolts 22 from being disengaged from the positioning hole 51a or 51b of the rack column 50 due to unexpected back and forth movement. Therefore, the slide rail bracket 2 can be firmly assembled on the rack column 50.

One of the features of the present disclosure is that, the buckle component 40 is detachably assembled on the main body 10, and the buckle component 40 can be changed depending on different slide rail positioning structures. Referring to FIG. 9 and FIG. 10, the slide rail bracket 2 according to an embodiment of the present disclosure implements another buckle component 40 with another structure. In this embodiment, the buckle component 40 is further disposed with a fastening plate 42. The fastening plate 42 is connected to the front end of the buckle component 40 and substantially perpendicular to the main body of the buckle component 40, such that the fastening plate 42 is disposed in front of the main body 10 parallel to the front end surface of the main body 10 by a distance. Referring to FIG. 10, FIG. 11A and FIG. 11B, when the slide rail bracket 2 and the buckle component 40 are assembled on the rack column 50, the front of the rack column 50 can be blocked by the fastening plate 42. The fastening plate 42 is further provided with a fastening hole 421 which is substantially rectangular. The fastening hole 421 can be used with a hook 61 of a locking device 60. The locking device 60 is installed at an end of a movable rail of the slide rail 1. When the movable rail of the slide rail 1 retracts back into the inside thereof, the hook 61 of the locking device 60 engages into the fastening hole 421 so that the locking device 60 and the fastening plate 42 are combined together.
